EPA is taking direct final action to amend the Toxic Substances Control Act (TSCA) section 8(a) Inventory Update Reporting (IUR) regulations by adding 1,2,3-propanetriol (CASRN 56-81-5) to the list of chemical substances in 40 CFR 710.46(b)(2)(iv) which are exempt from reporting processing and use information required by 40 CFR 710.52(c)(4). EPA has determined that the IUR processing and use information for this chemical is of low current interest. Manufacturers and importers of the chemicals listed in 40 CFR 710.46(b)(2)(iv) must continue to report manufacturing information.
